Product Name: UL Shape Mosi2 Heater Used for Electric Furnace Name: Mosi2 Heater Max Temperature: 1700c Trademark: SHIBO Transport Package: Wooden Boxes Specification: SGS Origin: Zhengzhou Product Description UL Shape Mosi2 Heater Used for Electric Furnace1.Molybdenum disilicide(MoSi2) heating elementis a resistance generate-heating component made from MoSi2or the basic material. It is used in high temperature under the oxidizing atmosphere, it looks like glass in its surface and form a light SiO2glass film which can protect the element not to be oxidized. So this kind of element has unique effect for resisting oxidization in the high temperature. It is used to the highest temperature up to 1800°Cduring oxidizing atmosphere. And the applicable temperature is 500-1700°C.2.Resistance propertyThe resistivity of element rapidly rises as the temperature rises. Under normal operating conditions, generally the element resistance doesn't change with the service time changing. So the old and new elements can be mixed used.3.Phiscal propertyVolume Density5.5g/cm3Porosity7.40%Bending Strength15-25kg/cm3Water absorption1.20%Vickers Hardness(HV)570kg/mm2Heating Elongation Rate4%4.Chemistry propertyMoSi2heating element is used in the high temperature under oxidizing atmosphere. It will form the SiO2film which can keep the element from being melted. When the temperature of element is more than 1700°C,the MoSi2heating element must not be used in the temperature between 400°Cand 700°Cfor a long time; otherwise the element will be cremated under the strong oxidizing function in the low temperature.DetailsType:1700C,1800CShapeU,W,ROD,UJL,WJL,andotherspecialshapeDiameters3/6,4/9,6/12,9/18,12/24mmLengthsUpto2000mmUsedtemperature1300Cto1800CMax.UsingtemperatureInoxidizingatmosphere,itcanreach1800COperationtemperatureindifferentatmosphereAtmosphere1700type1800typeNo2,O2,CO2,Air17001800He,Ar,N16501750SO216001700Co,N211501150WetH215001600DryH213501450ApplicationMoSi2heatingelementisusedinthefurnacetemperaturefrom1300Cto1700C.Itisextensivelyusedintheindustriesofmetallurgy,magneticmaterials,glass,ceramicrefractory,crystalelectronicdevice,industrialfurnacemanufacture,labfurnace,Laboratoryfurnace,industryfurnace,glassfurnace,ceramicfurnaceetc.
